Hyundai Santa Fe: Air conditioning System / A/C Pressure Transducer. Repair procedures
•
|
Before measuring the pressure of the refriferant line, check
whether the refrigerant amount is charged in accordance with
the specified charging amount.
(Refer to Heating, Ventilation, Air Conditioning - "Specifications")
|
|
1. |
Turn the ignition switch OFF.
|
2. |
Install the refrigerant recovery/recycling/charging system.
(Refer to Air Conditioning System - "Repair procedures")
|
3. |
Turn ON the ignition switch, put into operation the air conditioner.
|
4. |
Calculate the reference voltage of the Recovery/Recycle/Recharge machine
high pressure value using the formula below.
Reference voltage (V) = 0.0088 * pressure(psi) + 0.37
|
|
5. |
Measure the sensor output voltage between terminal "1" and "2".

6. |
If the reference voltage value and the sensor output voltage value are
close to each other, the air conditioner pressure transducer is normal.
|
7. |
If 0V is output or the reference voltage value and sensor output voltage
value are not close to each other, replace the air conditioner pressure
transducer.
• |
Check if the output voltage changes when the high pressure
value of the refrigerant line changes.
|
|
|
1. |
Disconnect the negative (-) battery terminal.
|
2. |
Recover the refrigerant with a recovery/charging station.
|
3. |
Disconnect the A/C pressure transducer connector (A).
|
4. |
Remove the A/C pressure transducer (A).
Tightening torque :
10 - 12 N.m (1.02 - 1.22 kgf.m, 7.4 - 8.8 lb-ft)
|
• |
Be careful not to bend the liquid & suction pipe.
|
|
|
5. |
Install in the reverse order of removal.
• |
When installing, replace it with a new O-ring (A).
